11-01-12 Astronomers have released the largest-ever colour image of the whole sky, stitched from seven million images, each made of 125 million pixels. 天文学家最近发布史上最大的整个天空的彩色照片,这张照片由700万张照片拼接而成,每张照片有1.25亿个像素。 Succ...
11-01-10 The surprising discovery of a supermassive black hole in a small nearby galaxy has given astronomers a tantalizing(撩人的,挑逗性的) look at how black holes and galaxies may have grown in the early history of the Universe. Finding a black hole a m...
10-11-23 Astronomers find cosmic dust annoying when it blocks their view of the heavens, but without it the universe would be devoid of(缺乏) stars. Cosmic dust is the indispensable(不可缺少的) ingredient for making stars and for understanding how primor...
10-11-19 Over the last 15 years, astronomers have detected nearly 500 planets orbiting stars in our cosmic neighbourhood, but none outside our Milky Way has been confirmed. Now, however, a planet with a minimum mass 1.25 times that of Jupiter has been discov...
10-11-11 Peace is the curious name given to a pair of interacting and merging galaxies that lie around 220 million light-years away in the constellation(星座,荟萃) of Aquarius. It is also known as NGC 7252 and Arp 226 and is just bright enough to be seen...
10-11-10 NASA's Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure centered in the Milky Way -- a finding likened in terms of scale to the discovery of a new continent on Earth. The feature, which spans 50,000 light-years, may be the...
10-10-14 The first galaxies formed before the Universe was less than one billion years old and were much smaller than the giant systems including the Milky Way that we see today. So somehow the average galaxy size has increased as the Universe has evolved. G...
10-07-01 Many of the Milky Way's ancient stars are remnants(残留) of other smaller galaxies torn apart by violent galactic(银河的) collisions around five billion years ago, according to researchers at Durham University. Scientists at Durham's Institute f...
10-05-28 A surprising discovery that hydrogen gas clouds found in abundance(充足的,大量的) in and above our Milky Way Galaxy have preferred locations has given astronomers a key clue about the origin of such clouds, which play an important part in galaxy...
10-05-26 A team of astronomy researchers at Rochester Institute of Technology, Florida Institute of Technology and University of Sussex in the United Kingdom, find that the supermassive black hole ( SMBH超重黑洞 ) at the center of the most massive local gala...
